The Oregon 1200-Z Industrial Stormwater General Permit has been renewed. Current permit registrants do not have to submit renewal applications; however, each facility must revise its Stormwater Pollution Control Plan (SWPCP) to meet the requirements of the renewed permit. The revised SWPCPs are due to Oregon DEQ by August 31, 2021.
The renewed 1200-Z stormwater permit has several changes, including revised benchmarks, changes to Category 5 303(d) list impairment monitoring requirements, additional sampling observations, providing verification of existing mass reduction measures, and allowing Tier II corrective actions to be imposed during any year of the 5 year permit cycle.
Previously implemented Tier II mass reduction measures must be verified by an Oregon PE or CEG, and the stamped certification provided to DEQ by December 31, 2021.
Farallon is working to educate our existing clients about the new permit requirements, and to begin SWPCP revisions to meet the August deadline. Please reach out if you would like to discuss your facility’s needs.
